CVE-2024-50028

Local system crash via unreferenced thermal zone

Published Oct 21, 2024 · Updated Aug 5, 2026

Use-after-free in Linux kernel 5.9 through 6.11.3 and 6.12-rc1 through rc2 allows local users to crash via thermal netlink requests. thermal_zone_get_by_id() returns a zone pointer without taking a device reference, allowing concurrent unregister to free it before netlink callers finish. Exploitation requires low-privileged local access and concurrent zone removal, and the documented consequence is limited to availability.
